There are generally two methods: one uses sulfuric acid to get to a low pH and sodium metabisulfate to reduce it, the other ferrous sulfate and alkaline pH. In either case, you'd have to then neutralize the wastewater back to neutral. Cr is fairly easy to trace through a sewer system; that means if you dump it, be prepared to spend some time in jail.
